366 MICHIGAN SURVEY, 1908. 



on tlie 6th. They were frequenting the clearings, and the immature speci- 

 men procured was taken near one of the old houses at the first clearing. 

 Upon our return to this locality on August 16 none were seen and they 

 were absent until August 31, when a large wave of Savannas struck the 

 island. For the remainder of my stay these sparrows were present, but 

 the majority had passed on to the south, either slowly or with some of 

 the other large waves. This species was very partial to the clearings 

 and was especially abundant along the road where the very short grass 

 did not interfere with their motions. The birds were quite tame and even 

 entered the houses by the open doors and windows. During one day of 

 the large wave a dozen or more were thus caught in the house I was liv- 

 ing in, most of these entering my work room. 



65. ZonotricMa leucophrys (554). White-crowned Sparrow. 



Range: North America at large, breeding chiefly in the Rocky Moun- 

 tains, the Sierra Nevada and northeast to Labrador. South in winter to 

 the Valley of Mexico. 



Stations: Washington Harbor, clearings and burned area, I, '04. 



Migration : September 12 on. 



This year the White-crowned Sparrow was much later in migration 

 than in 1904, as none were seen until September 12 while the first date of 

 the previous season was September 1. They were quite rare and were 

 never seen in flocks of more than 5 or 6. The clearings, roadside, and old 

 burnings were the favorite resort, but occasionally they were found 

 busily scratching among the fallen leaves along the river,

 England northward, and winters from Massachusetts southward. Ac-

The White-throated sparrow was very common throughout the Island, 

 where it inhabited the open swamps and borders of rock clearings, al- 

 though it was found in limited numbers in nearly every station ex- 

 amined. It can easily be considered one of the birds of general dis- 

 tribution on the island, chiefly frequenting certain habitats but not by 

 any means restricted to these specific environments. These sparrows were 

 seldom found feeding in the clearings any distance from shelter, but 

 were usually seen along the borders of the forest or in the more open 

 areas. Low, damp places where the decaying leaves formed a thick
